Lovely large collection of vintage carved stone fruit... this is all onyx or marble, I think. Made in Mexico, not Italian alabaster. It's dyed, not natural stone colors, colors beautifully shaded over the natural color variations of the stone.
These pieces are mostly around life-size (bananas 6" long). The tiny pineapple is missing it's top, this was probably plastic, we think. There's twenty-one pieces in all, shown altogether in the first photo.
